the AC motor drive decelerates to Minimum Output Frequency (Pr.1-05)
according to the deceleration time set in Pr.1-10 or Pr.1-12 and then stops.
the AC motor drive stops the output instantly upon command, and the motor
free runs until it comes to a complete standstill.
It is recommended to use "ramp to stop" for safety of personnel or to prevent
material from being wasted in applications where the motor has to stop after
the drive is stopped. The deceleration time has to be set accordingly.
If motor free running is allowed or the load inertia is large, it is recommended to
select "coast to stop". For example: blowers, punching machines, centrifuges
and pumps.
